of a substance from a liquid into a gas at a given pressure (often atmospheric pressure). Liquids may change to a vapor at temperatures below their boiling points through the process of evaporation.

To explore and work in space, human beings must take their environment with them because there is no atmospheric ... air pressure is no longer sufficient to keep body fluids from boiling.

A small amount of water is added to an aluminum soda can and brought to boiling ... The water gas molecules will occupy all the space inside the can since the air molecules have been pushed out. The ...

The gas must first be cooled to its boiling point ... The boiling point of water is 100 °C at normal atmospheric pressure, at sea level. At higher altitudes, the air pressure is lower, and ...
